cpuidle, intel_idle: Fix CPUIDLE_FLAG_IRQ_ENABLE *again*
So objtool found this bug:
vmlinux.o: warning: objtool: intel_idle_irq+0x10c: call to trace_hardirqs_off() leaves .noinstr.text section
As per commit 32d4fd5751ea ("cpuidle,intel_idle: Fix CPUIDLE_FLAG_IRQ_ENABLE"):
"must not have tracing in idle functions"
Clearly people can't read and tinker along until splat dissapears.
This straight up reverts commit d295ad34f236 ("intel_idle: Fix false
positive RCU splats due to incorrect hardirqs state").
It doesn't re-introduce the problem because preceding patches fixed it
properly.
Fixes: d295ad34f236 ("intel_idle: Fix false positive RCU splats due to incorrect hardirqs state")
